I bought a new rod and reel, Scott A3 and Galvan Torque 4wt, and am now looking for line. I am buying from BassPro and they sell Sharkskin, RIO LT, RIO Gold, and GPX. All of which I have heard are good. Any recommendations on which one would work best with my setup. I fish in NC in small to medium streams.

I have cast Rio Gold and SA Mastery trout on a 9ft 5wt A3. Each has a slightly different feel but both were excellent on the rod. As much as i like rio products i am leaning slightly towards recommending the the SA line. I would steer away from the GPX as the half weight heavier lines would be too much for the rod. A presentation line like the Rio LT would be nice if you were going pure dry fly.
